This should clear some things up. An article from Seattle's "The Stranger":
The Stranger: Are you a stoner? I’m thinking of the song on your new album, Hissing Fauna, Are You the Destroyer?, about “the chemicals.”
Kevin: Yeah, that has nothing to do with drugs. That's the chemicals in your mind.
The Stranger: Serotonin?
Kevin: Yeah. I went through this chemical depression, and that's when I was writing a lot of the songs for Hissing Fauna. They're all songs about that experience. And I was experiencing it in the moment that I was writing the songs, and sort of asking myself: What the hell is going on? Why are you all of a sudden totally paranoid and plagued by these anxieties? And why is everything so distorted and confusing and fucked up? My lifestyle hadn't changed that much. And then I realized, well, there's something going on inside of me that I don't have control over, and then you realize how vulnerable you are to these things, these elements that you can't understand, or unless you go on medication and get it under control. It's like you're being betrayed by your body.
